Abstract: PROBLEM TO BE SOLVED: To provide a transparent, heat-resistant thermoplastic resin composition having adjusted refractive index and compatibility, having excellent transparency, and excellent in the balance of heat resistance, impact resistance and molding processability. SOLUTION: This transparent, heat-resistant thermoplastic resin composition consists mainly of (A) a rubber-modified styrenic resin, (B) a heat-resistant resin having a Vicat softening point of >=120 deg.C, and (C) one or more other thermoplastic resins. Therein, the transparent, heat-resistant thermoplastic resin composition satisfies the inequality: |nDA1-nDm|<=0.01, wherein nDm=(wA2×nDA2+wB×nDB+wC×nDC)/(wA2+wB+wC). Therein, nDA1, nDm, nDB, nDC are the refractive indexes of the rubber portions of the component A, the matrix portion of the component A, the component B and the component C, respectively, and wA1, wA2, wB, and wC are the weights (wt.%) of the rubber portion of the component A, the matrix portion of the component A, the component B and the component C, respectively.  The matrix of the component A is thermodynamically compatible with a mixture comprising the components B and C. The 3 mm thick flat plate molded product of the thermoplastic resin composition preferably has a whole light transmittance of >=75%. Since the refractive index of the thermoplastic resin composition is adjusted in such the manner as above, the refractive index can easily finely be adjusted.

IPC: G03G9/107
Filed: 1987-12-17
Abstract: PURPOSE:To easily remove defective carriers by allowing a magnetic force and an electrostatic force on carrier particles at the same time and classifying carrier particles on which no sufficient magnetic force operates. CONSTITUTION:An insulating dielectric member 17 which is charged electrostatically to a predetermined polarity is brought into contact with carrier particles 16 which are conveyed on a sleeve 15 through the rotation of the sleeve 15 and magnetic roller 14 of a developing device to remove weak magnetic carriers. In this case, the magnetic force FM generated by the magnetic roller 14 and the electrostatic force Fc generated by the insulating dielectric member are made to operate on the carrier particles 16 at the same time, and carrier particles which satisfy FM<Fc are stuck on the insulating dielectric member 17 from the sleeve 15 to classify the weak magnetic carriers as defective carriers. The weak magnetic carriers are easily removed completely by the same model with a development part after the classifying process in the manufacture of resin carriers, so an excellent output having no stain at its image background part is obtained.

Title: Low frequency therapeutic apparatus
Inventor: KOJIMA TAKESHI
IPC: A61N1/36
Filed: 1994-12-22
Abstract: PURPOSE: To enhance usability of a low frequency therapeutic apparatus by separately displaying a determined output level and therapeutic mode from a practical output level and therapeutic mode. CONSTITUTION: Intensity is determined by an intensity determining means 2 and speed is determined by a speed determining means 3 to determine an output level. The determined intensity and speed are displayed respectively in a display window 9 and 10. When a therapeutic mode is determined by a therapeutic mode determining means 4, a mode lamp is lighted to display the determined therapeutic mode. A practical output level and therapeutic mode are displayed by a display means 5. Accordingly, display of the determined output level and therapeutic mode is separate from display of the practical output level and therapeutic mode, and therefore, even when output and therapy different from the determined ones are conducted, a content of the practical output can be found.

Title: Rotary drive generating device employing permanent magnet
Inventor: ITO SAKAE
IPC: F03G3/00
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a relatively lightweight and compact rotating drive without requiring fuel nor involving intake or exhaust pollution by changing magnetic poles with a force smaller than a torque of a permanent magnet. SOLUTION: When an N pole and S pole of a hydraulic cylinder 5, which is provided outside the N pole and S pole on a shaft, repel and attract each other, a force to turn the shaft a half turn is generated. This force is delivered by way of a crankshaft to a hydraulic pump 4. Further, a magnet inside the hydraulic cylinder 5 is moved to generate again the forces of repulsion and attraction. All this causes the shaft to turn continuously. At this time, the force to move the magnet inside the cylinder must be smaller than the force that turns the shaft in order for the shaft to turn. The meet this requirement, the hydraulic pump and hydraulic cylinder are employed and, in addition, a packing is placed between magnets inside the cylinder to minimize resistance between magnets when magnets are moved. This allows a bearing to move the magnets smoothly.

Title: Graphic display device and its display method
Inventor: MINEMURA TOMOKAZU
IPC: G06T11/00
Filed: 1990-11-22
Abstract: PURPOSE:To accelerate display speed by dividing a quadrangular area, deciding the presence/absence of intersection with a display area in each divided quadrangular area, and performing clipping processing on only circular graphics in intersecting divided quadrangular areas. CONSTITUTION:A CDP 12 recognizes the area by a coordinate value, and coordinate data is attached on the display area 1 and the quadrangular area 3. The coordinate data is accumulated in a segment buffer 16 by a CPU 10, and the CDP 12 refers to the data. In such a case, it is checked whether or not the quadrangular area 3 is not entirely included in the area 1. When all the quadrangular areas 3 are included in the area 1, no clipping processing is performed on divided circular graphics (1/4 of circle) in the area 3, and all of them are displayed. Since other areas 3 are intersected with the area 1, the clipping processing are performed on them. Thereby, processing time for the graphic including a three-dimensional graphic can be shortened.
